Code examples

The following code example fails the check and will give a warning:

#include <stdint.h>

typedef int32_t (*pfn_i)(void);
extern int32_t func1 ( void ); /* Note: A function */
pfn_i pfn2 = func1; /* Non-compliant */

The following code example passes the check and will not give a warning about this issue:

#include <stdint.h>

typedef int32_t (*pfn_i)(void);
extern int32_t func1 ( void ); /* Note: A function */
pfn_i pfn1 = &func1; /* Compliant */
